Memorability of pre-designed and user-defined gesture sets
Abstract
We studied the memorability of free-form gesture sets for invoking actions. We compared three types of gesture sets: user-defined gesture sets, gesture sets designed by the authors, and random gesture sets in three studies with 33 participants in total. We found that user-defined gestures are easier to remember, both immediately after creation and on the next day (up to a 24% difference in recall rate compared to pre-designed gestures). We also discovered that the differences between gesture sets are mostly due to association errors (rather than gesture form errors), that participants prefer user-defined sets, and that they think user-defined gestures take less time to learn. Finally, we contribute a qualitative analysis of the tradeoffs involved in gesture type selection and share our data and a video corpus of 66 gestures for replicability and further analysis.

A gestural repertoire of 1-to 2-year-old human children : in search of the ape gestures
Kersken, Verena; Gomez, Juan-Carlos; Liszkowski, Ulf; Soldati, Adrian; Hobaiter, Catherine (2019-07) - Journal articleWhen we compare human gestures to those of other apes, it looks at first like there is nothing much to compare at all. In adult humans, gestures are thought to be a window into the thought processes accompanying language, ... -
GesturalOrigins : a bottom-up framework for establishing systematic gesture data across ape species
Grund, Charlotte Vicki Christina; Badihi, Gal; Graham, Kirsty Emma; Safryghin, Alexandra; Hobaiter, Cat (2023-03-15) - Journal articleCurrent methodologies present significant hurdles to understanding patterns in the gestural communication of individuals, populations, and species. To address this issue, we present a bottom-up data collection framework ... -
Referential gestures are not ubiquitous in wild chimpanzees : alternative functions for exaggerated loud scratch gestures

(2022-07) - Journal articleA fundamental aspect of human communication is our ability to refer to external objects and events through both words and gestures (such as pointing), yet the evolutionary origins of such signals remain obscure.
